I have a 2003 honda accord 2.4L I-Vtec (K24A4) with no spark. The engine ran but had a bad timing chain tensioner, which has been replaced with an OEM one. I pulled the motor and trans as it has 170k on it. I did a full check of everything to make sure all parts were in within tolerance. I put the motor and trans back in. Since then I get no spark and I cannot move the shifter out of park (Automatic)

The only thing I think it may be is the cam and crankshaft position senser's, could they be the cause of no spark?

. Check all under hood and under dash fuses with a test light or multimeter.

. Check for codes.

. Check the Crankshaft Position Sensor.

. Check the main ECM ground. Verify the CEL comes on and goes off normally.
